Best ResponseYou've already chosen the best response.0im sure as long as you just get an answer; you will continue to type in the same kind of problem over and over again :)

Best ResponseYou've already chosen the best response.0assuming x is real: \[5 \sqrt((x+1)^2)+6 = 21\] otherwise: x+1=3

Best ResponseYou've already chosen the best response.0the absolute value is the last thing to work on; how do you get that absolute value all by itself?

Best ResponseYou've already chosen the best response.0looking at this question, what is the other solution for x if it was not an absolute value?

Best ResponseYou've already chosen the best response.0the term "absolute value" means that there is a quantifiable value; something that can be measured. length, height, area, volume, distance are all examples of abslute values

Best ResponseYou've already chosen the best response.0in other words; an absolute value doesnt care about what direction the sign takes us in; it only cares about a quantifiable measure

Best ResponseYou've already chosen the best response.0a is always positive, you discount the negative answer.

Best ResponseYou've already chosen the best response.0sky, you isolate the absolute value just like you would isolate a variable. Llort, no you do not 'discount' the negative answer. It is a valid solution.

Best ResponseYou've already chosen the best response.0as a result; if we are determining any value for inside of the absolute value notation; we have to account for the positive and the negative results that occur within it

Best ResponseYou've already chosen the best response.0So if you have \[5x+1 + 6 = 21\] You want to isolate the term with the absolute value in it first. You do this by subtracting 6 from both sides of the equation.

Best ResponseYou've already chosen the best response.0What do you get when you subtract the 6?

polpak

Best ResponseYou've already chosen the best response.0No, \(5x+1 + 6  6 = 21 6\) \[\implies 5x+1 + 0 = 15\]\[\implies 5x+1 = 15\]

polpak

Best ResponseYou've already chosen the best response.0So now lets say that x+1 is something, lets call it k.. So we have \(5k = 15 \)\[\implies \frac{1}{5}\cdot5k = \frac{1}{5}15\]\[\implies k = 3\] And since we said k was x+1 we have \[x+1 = 3\]So what values can x have and still make this equation true?

Best ResponseYou've already chosen the best response.0I am assuming the other answer is x=4

polpak

Best ResponseYou've already chosen the best response.0x =4 is one solution yes, because 4 + 1  = 3 = 3
